Hello @kkmultimedia,
Currently, the option to change the “learn More text” on the button is not available in the theme.
But it can be done using the child theme. To how you can activate the child theme please refer to the below given link:

After creating the child theme, create the folder “template-parts” and then inside the folder create another folder “home”. Finally, create the file “latest-news.php” and paste below given code.

Now go to line no:45 and change the text as per your requirement.
Hope this helps.
Thank you.
